Abstract (en)

The convergence tube is for a stereo-microscope and has both observation beam paths inclined towards each other at a converg angle (alpha) and in both beam paths picture reversal components are provided. In both observation beam paths four flat reflecto (R1-R4) are provided and so arranged that on the first two reflectors (R1,R2) incident and exit axis beams (2) are located in a common plane (E1,2). The incident and exit axis beams on the third reflector (R3) cover a plane (E3) which encloses an angle (beta 1 = 90 degree alpha/4) with the common plane (E1,2). The incident and axis beams on the fourth reflector (R4) cover a plane (E4), which enclos an angle (beta 2 = alpha/2) with the third plane (E3).
